valign="top">Running Ubuntu 10.04 LTS Lucid Lynx, creating group names
to mount to a Windows share and the GUI is telling me I have some
illegal characters in the group names. <br>
<br>
Group names: <br>
<br>
"music_on_compaqd51c"<br>
"shared_video_on_compaqd51c"<br>
"software_on_compaqd51c"<br>
<br>
etc, etc<br>
<br>
I used the command line to create the groups, and got no errors but
when I used the GUI to verify I did the commands right, I got the error
about illegal characters. There are no other error messages, but I'm
just wondering about allowable characters, before I create more groups.

Oddly enough, Google didn't turn up any results for rules on user/group
names. <br>
<br>
As usual, thanks in advance..........<br>

<pre>man groupadd
on Ubuntu 10.04 gives this:</pre>
...<br>
CAVEATS<br>
It is usually recommended to only use groupnames that begin with
a<br>
lower case letter or an underscore, followed by lower case
letters,<br>
digits, underscores, or dashes. They can end with a dollar sign.
In<br>
regular expression terms: [a-z_][a-z0-9_-]*[$]?<br>
<br>
On Debian, the only constraints are that groupnames must neither
start<br>
with a dash (-) nor contain a colon (:) or a whitespace (space:
, end<br>
of line: \n, tabulation: \t, etc.).<br>
<br>
Groupnames may only be up to 32 characters long.<br>
...<br>
<br>
Which would seem to indicate that the underscores are OK. Is it
possible that the groupnames in your example actually start and end
with the quotation marks? That would be an illegal character. Also all
letters must apparently be lowercase.<br>
